Perhaps you should try some spelling variations:
"modified quadratic optimization algorithm" » "modified static optimization algorithm", "modified quadratic optimization algorithms", "modified quadratic optimisation algorithm", "modified quadratic estimation algorithm"
"modified parameter optimization algorithm" » "modified parameter optimization algorithms", "modified parameter optimisation algorithm", "modified parameter estimation algorithm", "modified parameters optimization algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified quadratic optimization algorithm") or ("modified parameter optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified quadratic optimization algorithm") OR ("modified parameter optimization algorithm"))*.
• Removing quotes may allow a broader search: (( modified quadratic optimization algorithm ) or ( modified parameter optimization algorithm ))*.
